To all whom it may concern.-

Be it known that I, EMILE RUELLE, manufacturer, of Blane Misseron, French Republic,have in vented Apparatus for Drying Phosphates, &c., (for which I have obtained patents in Belgium,February 18,1887, No.76,39l; July 11, 1890, No. 91,226; October 23, 1891, No. 96,924; December-6, 1892, No.102,436, and July 22, 1893,No.105,665,and in France, January 28, 1887, No. 181,103, and January 14, 1893, No. 218,608,) of which the following is a specification.

The present invention consists of an apparatus for the drying of phosphates or other mineral, animal, or vegetable matters after such materials have been washed.

In the accompanying drawings, Figures 1 and 2 are respectively an elevation and a plan of the apparatus for drying the washed products.

This drying apparatus consists of two truncated cones and 26 of considerable length as compared to their diameter, being arranged concentrically one within the other with their inclination reversed. At one end these cones are connected rigidly together and closed I with the exception of a central opening communicating with the flue of a furnace 27. This is provided with opposite chambers, into one of which air is forced by a fan, and which are connected by arched pipes, so that the air in passing through them to the opposite chamber becomes heated, being discharged thence into the inner conical drum. The internal surfaces of the drums have angle-iron ribs 28 of helical form. The end of the inner cone opposite that communicating with the furnace is provided with a charging-hopper 29, having a regulating device for controlling the entrance of the material. The outer cone has a ring 30, which can slide on the internal cone, so as to allow of independent expansion and contraction. In this ring are openings through which the dried material escapes. Near these discharge-openings, within the annular space between the two cones, are arranged crushing-balls 31, guided by metal rings fixed to the internal cone, the before-mentioned helical ribs 28 being interrupted at these points. The outer cone has a toothed ring 32 fixed on its outer surface, with which gears a driving-pinion through which the double cone receives a rotary mo tion. The outer cone also has circular rails 33, that run on stationary rollers carried in bearings on the foundation. At 34 is provided a damper which serves to regulate the passage of the combustion-gases to a chim-' ney. (Not shown in the drawings.) It also serves as a baffle-plate for retaining. the light particles that would be carried ofi by the draft, these particles being deposited at the bottom of the box, from which they are removed through side doors. If the combustion-gases are proved to be liable to injuriously affect the material to be dried, they may be conducted away by a central flue passing right through the drums instead of entering directly into the latter. The materials are introduced through the hopper into the inner cone, along which they travel in the contrary direction to the hot gases entering through/the other end. In traveling along the materials are raised up bythe helical angle-iron ribs 28 and allowed to fall again, thus exposing them to a considerable extent to the action of the hot air. On arriving at the end of the inner cone they pass into the outer cone through openingsO, formed in the sides of the former, and then travel back again in the latter, eventually escaping through the openings of thering 30, whence they fall into a collecting-pit, from which they are removed by suitable means.

I claim as my invention- In apparatus for treating phosphates and the like, a drying apparatus comprising two rotary concentric truncated cones having their inclinations reversed, crushing-ballsbetween the two cones, angle=irons secured to one of the cones to guide the said crushingballs, the two cones communicating with each other at one end only, this end of the apparatus being provided with a furnace having a flue opening into the inner cone, and means name to this specification in the presence of for forcing air into the inner cone, the other two subscribing Witnesses. end of the inner cone being provided with a charging hopper, and a chimney leading therefrom and having a damper, all substantially as set forth.

In testimony whereof I have signed my EMILE RUELLE. Vitnesses:
